Product Description

High Purity Vinyl Ethylene Carbonate 99.5% CAS 4427-96-7 VEC Colorless transparent liquid for Li-ion battery additive

Description

Electrolyte additive for lithium ion batteries to enhance the cycling performance of the battery, It can form SEl films on the surface of positive and negative electrodes and effectively inhibit electrolyte decomposition. Can also be used for the synthesis of functionalised polymers

Application

Used as a highly reactive film forming additive in lithium secondary batteries. VEC has higher dielectric constant, higher boiling point and flash point, which is conducive to improving the safety performance of lithium ion batteries. VEC begins to decompose at 1.35V, and can form a stable and dense SEI film on the flake graphite, effectively preventing PC and solvated lithium ions from being embedded together between the graphite layers, and inhibiting the decomposition of the electrolyte to a minimum, thus improving the charging and discharging efficiency and cycling characteristics of lithium-ion batteries. When a certain amount of VEC is added to the electrolyte at a suitable temperature, the cycling performance of the cathode metal is significantly improved. After multiple charge and discharge cycles, the retained discharge capacity can be increased from 68.8% to 84.8%. According to the test results, adding VEC can make the CO2 peak disappear during the second charge-discharge cycle, and significantly reduce the CO2 release. This shows that both the yin-yang poles form a stable SEI layer with the participation of VEC..
